Narrative:
In sum: an air carrier MD80 was scheduled to fly mco-iah-lax. The EPR on engine #1 was 0.15 lower than normal with the engine anti-ice on the first leg. This was passed on to iah maintenance along with the fact that there was staining on the forward fuselage from the lavatory drain. A ramp service man told the reporter that there appeared to be a leak in addition to the reporter's preflight inspection. Air carrier maintenance assured the flight crew that the aircraft was 'ok for flight.' passing bkx, the #1 engine failed with a popping sound, deceleration and a slight airframe shudder. The engine instruments confirmed an engine shutdown. A cabin attendant confirmed that there was an engine problem, an emergency was declared with a request to divert to phx. Air carrier maintenance test ran the engine and found that it ran perfectly. Maintenance also tended to the leaking forward lavatory service drain. The reporter and the aircraft continued to lax without further incident. The reporter does not know why the engine lost power. He expected to see a 'significantly damaged engine,' but no damage was found. The reporter is very pleased with his air carrier's new QRH for emergency sits, but he is highly displeased with the amount of radio frequency changes that had to be made in the 15 mins to touchdown -- at least 7 handoffs interfering with checklist completion. He suggests a single frequency assignment for emergency sits.

Title: AN ACR MD80 FOR RPTS THAT ONE OF HIS ENGS HAD AN INFLT SHUTDOWN FOR NO APPARENT REASON. THERE WAS NO ENG DAMAGE.
Narrative: IN SUM: AN ACR MD80 WAS SCHEDULED TO FLY MCO-IAH-LAX. THE EPR ON ENG #1 WAS 0.15 LOWER THAN NORMAL WITH THE ENG ANTI-ICE ON THE FIRST LEG. THIS WAS PASSED ON TO IAH MAINT ALONG WITH THE FACT THAT THERE WAS STAINING ON THE FORWARD FUSELAGE FROM THE LAVATORY DRAIN. A RAMP SVC MAN TOLD THE RPTR THAT THERE APPEARED TO BE A LEAK IN ADDITION TO THE RPTR'S PREFLT INSPECTION. ACR MAINT ASSURED THE FLC THAT THE ACFT WAS 'OK FOR FLT.' PASSING BKX, THE #1 ENG FAILED WITH A POPPING SOUND, DECELERATION AND A SLIGHT AIRFRAME SHUDDER. THE ENG INSTS CONFIRMED AN ENG SHUTDOWN. A CABIN ATTENDANT CONFIRMED THAT THERE WAS AN ENG PROB, AN EMER WAS DECLARED WITH A REQUEST TO DIVERT TO PHX. ACR MAINT TEST RAN THE ENG AND FOUND THAT IT RAN PERFECTLY. MAINT ALSO TENDED TO THE LEAKING FORWARD LAVATORY SVC DRAIN. THE RPTR AND THE ACFT CONTINUED TO LAX WITHOUT FURTHER INCIDENT. THE RPTR DOES NOT KNOW WHY THE ENG LOST PWR. HE EXPECTED TO SEE A 'SIGNIFICANTLY DAMAGED ENG,' BUT NO DAMAGE WAS FOUND. THE RPTR IS VERY PLEASED WITH HIS ACR'S NEW QRH FOR EMER SITS, BUT HE IS HIGHLY DISPLEASED WITH THE AMOUNT OF RADIO FREQ CHANGES THAT HAD TO BE MADE IN THE 15 MINS TO TOUCHDOWN -- AT LEAST 7 HDOFS INTERFERING WITH CHKLIST COMPLETION. HE SUGGESTS A SINGLE FREQ ASSIGNMENT FOR EMER SITS.
